Bug #17122 Updated: Values set in _SESSION doesn't stick

ID: 17122 Updated by: goba@php.net Reported By: mats@cdmedia.nu Status: Verified Bug Type: Documentation problem Operating System: Linux RH 7.2 PHP Version: 4.2.0 New Comment: As session variables are subject to be registered as global variables (if register_globals is on), and identifier names (including variable names) cannot begin with a numeric character, it's not too hard to see that session variables should not begin with a number. Basically session variables should follow naming ruiles for identifiers IMHO. Previous Comments: ------------------------------------------------------------------------ [2002-07-05 15:46:23] scott@abcoa.com Whoop! One more thing! $_SESSION[CUSTOMER_ID] does work on page 1 also! Didn't include that as Example #3 on page 1. ------------------------------------------------------------------------ [2002-07-05 15:43:30] scott@abcoa.com I struggled with the $_SESSION problem for almost a week. When I read this report, that is when reality hit me. In the comment written by "sniper@php.net" saying that I'm not suppose to use the numberic value. I'm using PHP 4.2.1 and AIX 4.3.3. Here's the example that work which should not have work at all. See the "//This one work!! (Numberic Value)". Why do I have to spend almost a week struggling over it? I read many documentation about $_SESSION vs. session_register() with the register_global turned off, but they say nothing about the numeric value that aren't allowed to be used? Thanks, FletchSOD --clip-- //-------Page 1--------- define(CUSTOMER_ID,0); define(CUSTOMER_NAME,1); define(STREET,4); define(CITY,5); define(STATE,6); define(ZIP_CODE,7); $salt = strtoupper(md5(uniqid(rand()))); session_id($salt); session_start(); //$result is from odbc_exec odbc_fetch_into($result,$_SESSION,1); //Example #1 print_r($_SESSION); //This one work!! (Numeric Value) //Example #2 echo $_SESSION[0]; //This one work also! (Numberic Value) header("Location: https://www.whatever.com/page2.php"); //-------Page 2--------- session_start(); print_r($_SESSION); //This one does not work! --clip-- ------------------------------------------------------------------------ [2002-06-28 09:11:18] sniper@php.net You're not supposed to do that. But it should indeed be documented. ------------------------------------------------------------------------ [2002-06-28 06:15:31] mats@cdmedia.nu Ok, that seems reasonable. (Even though I cannot find anything in the manual that explicitly states that numerical indexes are unsupported) However, the setting of a numerical index seems to silently break something, since the other values in the example are affected as well. Is this really the intended behavior? ------------------------------------------------------------------------ [2002-06-27 23:07:05] sniper@php.net Numerical indexes in $_SESSION are NOT supported. (and never will be) User error -> bogus. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
